Maybe that's just the natural progression for technologies that are dependencies of other technologies. As a software business you don't want to depend on too many pieces of software (or hardware) that you have little to no control over. Linux is the best example of a solution for that problem - even the tech giants won't bother making their own OS anymore if there is already one out there that they can use and modify. And ISAs (RISC-V) will probably follow that route too. What's interesting though is that businesses seem to be unable to initiate that progress on their own. You need those vocal FOSS people for that, who will tirelessly drag technology towards an ideal we'll never reach... but nobody else will get the ball rolling. FOSS as the basis for entire ecosystems of businesses that would have never existed without it makes total sense, but no business will create it out of thin air. I think this gradual opening up like with TimescaleDB is simply an effect of the wind blowing in that direction. Few will be going full speed, but nobody wants to be left behind.
